Off-site <br />sedimentation and surface runoff in excess of the historic flow will be controlled. The primary <br />control structure for the entire operation is the Magic Mountain Reservoir. All of the internal <br />drainage eventually finds its way to this structure. <br />During the mining operation, the open pit has a sump in the lowest bench to collect any water <br />that is in turn pumped to the Magic Mountain reservoir. Potential sedimentation that may occur <br />around the perimeter of the mine is controlled by a series of sedimentation and settling ponds. <br />Spec cation Aggregates <br />OMG /!2 Permi!
